Brad Pitt and Angelina Jolie are engaged. After years of marriage rumors followed by repeated denials, the longtime Hollywood power couple will tie the knot.

“Yes, it’s confirmed. It is a promise for the future, and their kids are very happy. There’s no date set at this time. Brad designed the ring,” confirmed a rep to theAssociated Press.

Brad and Angelina, or at least Brad knew this day was coming despite repeatedly dodging marriage rumors. Beverly Hills jeweler Robert Procop revealed that the ring was a year in the making! He told the Hollywood Reporter,

“Brad had a specific vision for this ring, which he realized over a yearlong collaboration. He wanted every aspect of it to be perfect, so I was able to locate a diamond of the finest quality and cut it to an exact custom size and shape to suite Angelina’s hand. Brad was always heavily involved, overseeing every aspect of the creative design evolution. The side diamonds are specially cut to encircle her finger. Each diamond is of the highest gem quality.”

Already predicted to be the next Kate and William wedding Angelina sparked the media fire when she was spotted wearing the ring last Wednesday at a private viewing of the Los Angeles County Museum of Art’s Chinese Galleries.

Brad and Angelina’s six children will likely take credit after prodding their parents for years to get married. No wedding date has been set.

Jolie, Pitt and their son Pax attended a private viewing at the Los Angeles County Museum of Art on Wednesday, and the Oscar-winning actress was wearing the large, rectangular diamond ring on her left hand.

Pitt's manager confirmed the news to The Associated Press on Friday, after Jolie had been photographed wearing a large diamond ring on her engagement finger.

Cynthia Pett-Dante said that there is not a wedding date "at this time." She also said that the engagement "is a promise for the future."

Pitt and Jolie have been a couple since 2005, and are raising six children – three adopted and three biological – together, but they have never married.

Ms Pett-Dante also said that "their kids are very happy.

A spokesman for jeweller Robert Procop told Us Weekly: "I can confirm that, yes, Robert Procop did indeed diesgn an engagement ring for Angelina Jolie, designed in collaboration with Brad Pitt."

Pitt was previously married to Jennifer Aniston from 2000 to 2005, while Jolie has been married to Jonny Lee Miller from 1996-1999 and Billy Bob Thornton from 2000-2003.

The couple, who met on the set of Mr and Mrs Smith in 2005, are reportedly in discussions to once again work together. Jolie is being eyed by Ridley Scott for the lead female part in thriller 'The Counselor', written by Cormac McCarthy. Pitt is also reportedly lined up for a role in the film.

The Family

The 36-year-old mother-of-six had already adopted oldest son Maddox, 10, before she got together with Brad in 2005, but insists that until then, she only wanted a couple of kids.

She said: 'At first I was thinking of adopting two children, but I wasn't sure. 'I knew I didn't want to raise a large family on my own but when Brad came into my life and I came to know him, I discovered that he loved being a father and wanted to build a family with me. I didn't plan on having twins either!'

In addition to Maddox, the couple - who met on the set of 'Mr. and Mrs. Smith' while Brad, 48, was still married to Jennifer Aniston - also have adopted kids Pax, eight, and Zahara, seven, as well as biological daughter Shiloh, five, and three-year-old twins Knox and Vivienne. And Angelina admits she falls deeper in love with the 'Moneyball' actor every time she sees him with their children. She told OK! magazine: 'When we first met I appreciated how caring, sexy and how great a friend he was to me. 'But I also fell in love with the man who was a very loving father and how much he enjoys spending time with the children. 'When I see how much love is in Brad's eyes for the twins and for all our children, it's a very moving experience for me. When I see him with the children it makes me love him even more
